Description

[Detailed description of the invention] This invention relates to a woven tape for a slide fastener having metal fasteners or fasteners molded by injection molding of synthetic resin, and the raised edge of the tape on which the fasteners are attached is The raised edges ensure that the fabric remains in an elongated, almost rectangular shape with a thickness greater than its width, without being flattened during various processes, such as dyeing, from weaving to the mating process. The purpose is to provide it as a sticky tape.

Conventionally, for this type of tape, warp threads are attached along the entire outer periphery of a core material provided parallel to one side edge of the tape, and the weft threads used to weave the tape are woven together with the warp threads to create raised ridges. Those with edges are known.

However, this tape is wrapped around a drum or roller during the various processes that are carried out during the manufacturing of slide fasteners, such as the dyeing process, and this winding flattens the raised edges, making it easier to implant the fastening teeth. In this case, a part of the raised edge protrudes from the inside of the leg of the fastener, making the mounting of the fastener unstable and reducing the strength of the mounting.

This invention was devised to eliminate the above-mentioned conventional drawbacks, and embodiments will be described below with reference to the drawings.

1 and 2 show a first embodiment of the present invention,
Along one longitudinal edge of the tape main body 1 woven with warp threads 3 and weft threads 4, a core material 5 with a roughly circular cross section and a diameter larger than the thickness of the tape main body 1 is attached. A plurality of spliced warps 6, 6 are arranged in parallel on each of the upper and lower surfaces, and one of the weft threads 4 constituting the tape body 1 is interlaced with the spliced warps 6, 6 to form a hollow weave structure around the core material 5. By placing the
is woven integrally with the tape body 1.

Further, four weft yarns 4 are alternately interwoven with splicing warp yarns 6, 6 arranged on the upper and lower surfaces of the core material 5, respectively.

Furthermore, two weft yarns 4', 4'' located inside the four weft yarns 4 that alternately appear on the upper and lower surfaces of the core material are connected to a plurality of spliced warp yarns 6, 6 arranged on the upper and lower surfaces of the core material 5. They are inserted so as to be intertwined with the outermost splicing warps 6' and 6'' of each of them and reversed.

Therefore, the spliced warp yarns 6, 6 are reliably held by the weft yarns 4 and positional displacement is prevented, which is preferable in the present invention.

Incidentally, the core material 5 is formed of a knit cord having a twisted thread 7 at the center.

Compared to the core material made of twisted cord, the core material made of knit cord has a denser and tighter structure, so its shape is more likely to deform. Even if you tighten it, it will become a bulge and protrude from between the wefts,
It is preferable to use knitted cord as the core material in the present invention because it does not destroy the original shape of the core material. Also, FIGS. 3 to 6 show the first embodiment shown in FIG. Each cross-sectional view taken along lines BB, CC, and DD is shown to show the state of the hollow weave at each position.

FIGS. 7 and 8 show a second embodiment of the present invention, in which weft 4
It is woven so that two strands are hung alternately.

The other configurations are the same as in the first embodiment.

FIG. 9 shows a third embodiment of the present invention, in which among the plurality of splicing warps 6, 6 arranged on the upper and lower surfaces of the core material 5, the splicing warps 5a, 5a arranged at the center of each It is thicker than other warp threads.

The other configurations are the same as in the first embodiment.

FIG. 10 shows a fourth embodiment of the present invention, in which among a plurality of splicing warps 6, 6 arranged on each of the upper and lower surfaces of the core material 5, a splicing warp 6b located at the innermost side near the tape body 1; 6b is thicker than other warp threads.

The other configurations are the same as in the first embodiment.

FIG. 11 shows a fifth embodiment of the present invention, in which spliced warp threads 6,
This is a different way of interweaving the weft yarn 4 with respect to the weft yarn 6. Of the five spliced warp yarns 6゜6 arranged on the top and bottom surfaces of the core material, two spliced warp yarns on each side are considered as one. It is a bag weave in a state.

The other configurations are the same as in the first embodiment.

FIG. 12 shows a sixth embodiment of the present invention, in which thin sub-core materials 8, 8 are interposed between the core material 5 and the upper and lower portions of the core material 5 near the tape body 1. Although the state is the same as the example shown in FIG. 1, this may be interwoven as in the example shown in FIG. 2 or FIG. 11.

・Figure 13 shows the tape shown in Figure 1 with the attachment teeth 9 planted, and the raised edge 2 is attached to the attachment teeth 9.
It is clearly shown that the tape body 1 is inserted into the legs 10.10 of the tape body 1, and the distal ends of the legs 10.10 are in pressure contact with the tape body 1.

This invention has the above structure, and the core material 5 of the raised edge portion 2 is thicker than the thickness of the tape body 1, and the splicing warp threads 6, 6 are attached to the upper and lower surfaces of the core material 5, respectively. As shown in FIG. 2, the thickness h of the raised edge 2 is larger than the width a,
Since it is formed into a vertically elongated, almost rectangular shape, and the core material 5 is rounded, it is difficult to flatten during the various processing steps until the fastening teeth are attached to the tape, and when the fastening teeth are attached, the core material 5 is almost in the state as when manufactured. It has been shown through experiments that the tooth is maintained in a stable manner, and the tooth can be firmly planted in a stable state.

Furthermore, even if the core material is rounded, since the upper and lower splicing warp threads are interwoven with the weft threads, the lined state is not easily deformed and the state at the time of weaving is maintained.

Therefore, if a tape having the structure according to this invention is finished, there is no fear that the raised edges will deform into a flat state by the time they are planted, and an extremely good slide fastener can be provided.
